We've had a Bz4x for a few weeks and Husband noticed about a 10% drop on Tuesday when it was very cold, particularly at higher speeds on the A19.
On our Leaf we've only noticed an 8% decrease in efficiency in the freezing weather in comparison to the warmer weather a few months back (4.1mi/kWh vs 3.8mi/kWh). And that's without pre-heating the car on grid power on most days.
If they're able to pre-heat the buses while still on charge, I'd imagine the hit to efficiency wouldn't be too different.
